I am unable to see the appeal of a view in which there is no fact of the matter. It seems to me that there is a fact of the matter concerning the past, even if it is impossible for us to know. This is not similar to the case where sneezing alters two shadow variables, and it is impossible for us to meaningfully refer to variable 1 as opposed to variable 2; the past has a structure, so assertions will typically have definite referents.
